Evolving Economics of Bitcoin, Gold, Currencies

An inherent tension exists between the two major purposes of money. Currencies that are perceived as great stores of value, such as gold and bitcoin, make for poor mediums of exchange. By contrast, currencies that are effective mediums of exchange, such as fiat currencies used the world over, can make for dubious stores of value. Where a currency falls on the store of value versus medium of exchange spectrum influences its usefulness as a unit of account and a standard of deferred payment.
